Comment (by whyisjake):

 In [changeset:"46194" 46194]:
 {{{
 #!CommitTicketReference repository="" revision="46194"
 Multisite: Remove the redundant `blog_versions` table.

 As part of the Multisite installation process, a `blog_versions` table is
 created. This table is never read from (except immediately prior to
 updating it), it's only ever inserted into or updated. It is not used to
 determine which blogs need to be upgraded.
 This table was introduced in 3.0 when the WPMU schema was merged #11644
 and it appears the table has never been used in core and is therefore
 redundant and may as well be removed.

 Props johnbillion, nacin, ryan, johnjamesjacoby, whyisjake.

 Fixes #19755. See #41685.
